Hi I thought I'll write a little strategy guide,so the fastest way to get points in this mode is to shoot the guy most people shooting on if you're good at aiming (why?his HP will go down very fast and if you're a good shooter you might be the one who gets the kill and also if everyone shooting him you don't have to worry so much about someone shooting you from behind but always keep an eye on the radar) shooting someone who has a weapon that can't be used while running from the back can be a good idea too and if you shoot someone from behind and someone else shooting at him from the front he probably won't even notice that you're shooting at him,now if you have a bad weapon what you should do is try to shoot people from as far as possible and also never go into fight with someone who has a better weapon (unless he's got low HP),just run away until he leaves you..so that's it,I hope it helped.
